OpenAI announced the global public launch of its GPT-5.6 models on Thursday, July 9. This came after the US government lifted earlier access restrictions on the advanced AI family. The models include three versions. Sol is the flagship for complex programming, research, reasoning, and cybersecurity work. Terra offers performance close to the previous GPT-5.5 at half the cost. Luna serves as the most affordable option. Initially, OpenAI had limited GPT-5.6 to select organizations last month due to US cybersecurity concerns. The company shared plans with officials and conducted extra testing. Now the rollout expands preview access worldwide. OpenAI confirmed the move on X, with CEO Sam Altman noting the Sol launch. The models stay within safety boundaries while delivering stronger results in key areas.
